1. Scope

1.1 This test method covers a quality control test fornonvolatile content of latex vehicles. The specified time-temperatureconditions (180°C, 20 min) were selected to allowtest completion in 1 h orless. For latex vehicles used in certainair-dry or low-temperature bake coatings, as well as for thosethat contain temperature-sensitive materials, the use of a lowertemperature and other bake time will more accurately reflectthe effective nonvolatile content (Note 1). Alternative time-temperatureconditions should be agreed upon between theproducer and user.

NOTE 1--The test conditions of Test Method D 2369 (110°C, 60 min) have been found suitable for use with many latex vehicles.

1.2 This test method is not intended to be employed fordetermining the volatile organic content (VOC) of formulatedcoatings.

1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It isresponsibility of the user of this standard to consult andestablish appropriate safety and health practices anddetermine the applicability of regulatory limitations prior to use.
